And if the PSU's fault is that it is giving out too high a voltage, well pop goes yet another mobo. That imho is - seeing that 2 mobos have apparenty released the magic smoke - quite a possibility. Do, please. take care. Is it also a possibility that the new kinds of mobo require different, i.e. lower, voltages from that which the old one needed? Check the doco!!!! If that's the case, then I posit that what has happened is unfortunately to be expected. To get a PSU to function out of the comp's case, e.g. on a dummy load instead of a mobo you will have to connect the voltage sensing wire(s) to the load(s). Do use dummy loads, even if the're not 100% loads, because some PSU's don't like having no load at all. > If you can measure while the disks are spinning up, many extra > bonus points.
